D) Phosphorus

Plz hurry up!!

Data analysis has two prominent methods: qualitative research and quantitative research. Each method has their own techniques. Interviews and observations are forms of qualitative research, while experiments and surveys are quantitative research.

Answer:

The structure for 2 brormocyclopentan amine is given in attached file.

Explanation:

2-bromocyclopentamine (Figure attached) is a synthetic compound which is synthesized by substitution reaction of cyclopentamine and hydrobromide. Its molecular formula and molecular mass are C5H10NBr and 164.05 g/mol respectively.  It is a very reactive compound so it doesn’t available in pure form, it is present in market as a mixture of 2-bromocyclopentamine and Hydrobromide.

Properties:

Its boiling point is 115 °C.

Its melting point is  -75 °C.

It is highly flammable.

It is highly toxic.

It is irritant.

It is corrosive in nature.

The answer to this question is C.

Answer:

Explanation:

Hydrogen peroxide

Hydrogen peroxide is a chemical compound with the formula H₂O₂. In its pure form, it is a very pale blue liquid, slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic. Concentrated hydrogen peroxide, or "high-test peroxide", is a reactive oxygen species and has been used as a propellant in rocketry. Its chemistry is dominated by the nature of its unstable peroxide bond.

Chemical formula: H2O2

Density: 1.45 g/cm³

Boiling point: 302.36°F (150.20°C)

Average Molar mass: 34.01 g/mol

Melting point: 31.23°F (-0.43°C)

Legal status: Over-the-counter drug · Not evaluated by FDA

Water

Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H₂O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Two hydrogen atoms are attached to one oxygen atom at an angle of 104.45°.

Boiling point: 212°F (100°C)

Melting point: 32°F (0°C)

Chemical formula: H2O

Average Molar mass: 18.02 g/mol

IUPAC ID: Water

So probably C or D i dont know

Sorry if it is wrong

Answer:

ExplanatioHydrogen cannot exist in free state as hydrogen needs an electron to attain stability. If an element does not attain stability it cannot exist on its own. In Sun there are large number hydrogen atoms and helium atoms present this creates a lot of energy and nuclear fusions are occured. Gases that attain stability can normally exist on their own. E.g. Argon, Neon, Helium, Krypton and Xenon. Gases that cannot exist on their own are:

H2

O2

N2

Hope it helped a little......

The definition of a Lewis base is: C. a substance that accepts electrons to form a covalent bond.

What is a Lewis base?

A Lewis base can be defined as a specie of an ionic or chemical compound that contains an empty orbital which allows it to donate an electron pair (two or more electrons) to form a covalent bond.

This ultimately implies that, a Lewis base is a chemical substance that accepts an electron pair (two or more electrons) to form a covalent bond.

Examples of a Lewis base.

In Chemistry, some examples of a Lewis base include the following:

• CO

• ROH
